Adaptations for growth curvelife is different @ different points along curve (exponential phase- r strategy)
Habitatresources are plentiful, density dependent factor minimal, rapid pop'l expansion
Adaptationshigh pop'l growth rate"r", lots of kids per litter (clutch), early maturity, polygyny likely
Consequencesshort-life span, death rate soars when near K, pop'l cycles
Example of adaptations for growth curve "r"lemmings & white tailed deer & mule deer
Lemmingsincrease phase 1: females pregnant @ 20 days, have winter breeding in burrows under ice
Lemming "r" strategyduring peak and decline phase(2-3), only one litter per summer, individuals grow to 20-50% larger than increase phase
Lemmings disperseduring increase phase. most dispersers are small, sexual immature
